Congratulations have been pouring in ever since Mark Zuckerberg posted (on Facebook, of course) that he and his wife Priscilla Chan are expecting a daughter in a few months. It’s wonderful and all (mazel tov, you two!), but most people took a look at their photo and wondered, is that a dog—or a mop? »7/31/15 6:05pm Friday 6:05pm

Unlike a certain companion animal that will go unnamed, dogs lose their minds when reunited with their owners. But it’s not immediately obvious why our canine companions should grant us such an over-the-top greeting—especially considering the power imbalance that exists between the two species. We spoke to the experts… »7/31/15 3:08pm Friday 3:08pm

Meet Fritz. He’s a 125lbs Belgian Malinois employed as a Military Working Dog by the Air Force. They figured it’d be a good idea to get him to attack me so I could write you an article about it. Let’s see how that goes. »7/14/15 2:11pm 7/14/15 2:11pm

Clicker training has proved effective on virtually any animal, from pigeons to porpoises to people. If you were to train a pack of raptors, it likely is the method you would use. But, Chris Pratt gets it wrong in Jurassic World; here’s how to do it right. »6/22/15 4:33pm 6/22/15 4:33pm

Keeping a pet healthy requires resources and open space, and in the cities of the future both may be at such a premium that live pets will become a thing of the past. Australian researcher Jean-Loup Rault suggests robotic and virtual-reality pets may replace the real thing. »5/12/15 12:20pm 5/12/15 12:20pm

If you’re a detective who needs to find a corpse, there are lots of ways to look: you can comb the woods in a line search or hunt for hidden graves with ground-penetrating radar. In most cases, though, the most versatile and reliable method has four legs and a wet nose. »5/06/15 3:00pm 5/06/15 3:00pm

Tomorrow’s National Adopt A Shelter Dog Day. So, we’re here to remind you that there’s hundreds of thousands of new best friends just waiting on you to come save them. What are you waiting for, drones? »4/29/15 8:40pm 4/29/15 8:40pm

A couple months ago, Lara and I adopted an 8-year old Cocker Spaniel and named him Rufio. Can an older dog really involve less effort and energy than a puppy? And can one integrate as fully into an active family? This is our experience. »3/24/15 4:35pm 3/24/15 4:35pm

So far as awful ways to die go, being attacked by a rabid animal then dying a slow, painful death must rank near the top. And exactly that happens to 55,000 people every year. Here's how you (or your dog) can get rabies, what it does to your body as it kills you and what you can do to ensure neither of you gets it.»3/19/15 6:24pm 3/19/15 6:24pm

Eugenics is the now-defunct (and creepy!) practice of breeding supposedly superior humans to achieve genetic improvements while sterilizing undesirables. Sound familiar? It's the exact same thing we now do to dogs and it's responsible for a range of health and behavioral issues in them. — Ed. »3/17/15 7:24pm 3/17/15 7:24pm

When a decades old toy breaks down and stops working with no hope of repair, you usually just toss it or find some way to recycle the parts. But what if you're as attached to that toy as you were a pet? In Japan, people are giving Sony's robot AIBO dog actual funerals to say goodbye to their faithful, electronic… »2/26/15 11:11am 2/26/15 11:11am

Way up at the top of Northern California is a little piece of wilderness called The Lost Coast. It's too rugged to build on, meaning it's the last coastline here that's unspoiled. It's also dangerous, as you can see in this picture. Especially in winter, during a storm. Let's go backpacking! »1/13/15 2:08pm 1/13/15 2:08pm

I think my dog Amos—attentively listening above—understands me. I'm not talking about his hundred tricks learned thanks to these guys and the power of the clicker (he follows commands better than most kids.) I'm talking about true understanding. This video explains why this thought isn't crazy at all. »1/08/15 8:36pm 1/08/15 8:36pm
